Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application is related to and claims priority to U.S. Provisional Patent Application No. 62/469,149 filed Mar. 9, 2017, which is incorporated by reference herein in its entirety.

BACKGROUND OF THE INVENTION

The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.

TECHNICAL FIELD

The present invention relates generally to the field of valves of existing art and more specifically relates to a valve for use in cleaning pipeline systems.

RELATED ART

Pipeline systems need regular cleaning to maintain pipe integrity. This is typically done without stopping the flow of the product in the pipeline. The process is referred to as ‘pigging’. Pigging can be used for almost any section of the transfer process between, for example, blending, storage or filling systems. Pigging systems are already installed in industries handling products as diverse as lubricating oils, paints, chemicals, toiletries, cosmetics and foodstuffs. Current pig valve technology used to open an access port is generally complicated and time consuming. Additionally, the opening mechanism is subject to corrosion and damage and the valve's seal is subject to leakage and damage, which can be expensive for pipeline companies to replace. Additionally, current pig valve technology does not have any way to detect the presence of pressure in the pig valve. A suitable solution is desired.
U.S. Pat. No. 8,225,809 to Lee A. Krywitsky relates to a methods and apparatus for introducing a pig into a fluid system. The described methods and apparatus for introducing a pig into a fluid system includes an apparatus for introducing a pig into a fluid system. The method comprises providing a coupling in a fluid system. The coupling itself can include a sleeve coupled to a pipe and an end cap. The end cap may include a collar handle and at least one engagement member. The engagement member facilitates selective engagement of the end cap with the sleeve. The end cap is rotated relative to the sleeve to disengage the engagement member from the groove and to open the end cap relative to the sleeve. The groove is configured so that the engagement member can be opened only when the line is de-pressurized. A pig is inserted through the sleeve and into the pipe. The end cap is then coupled to the sleeve by engaging the engagement member with the sleeve and rotating the end cap relative to the sleeve.

DETAILED DESCRIPTION

As discussed above, embodiments of the present disclosure relate to a valve and more particularly to a valve with quick loader access port system and method as used to improve the valve for use in cleaning pipeline systems.
Generally, a pig valve is used in pipeline pigging (cleaning) operations as an access port for insertion and extraction of the cleaning pig. The quick loader access port allows for easy and quick opening of the valve for insertion and extraction of the pig. The integrated pressure alert valve advises that pressure is or is not present in the pig valve and if pressure is present, will relieve the pressure, unlock the quick loader port and allow access to the port opening. The quick loader access port opens with just a 40 degree turn of the handle, while current products use a threaded cap requiring many turns of the cap to open. The integrated pressure alert valve locking system prevents opening while under pressure. Current products do not necessarily have an integrated system.
Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4, various views of a valve 100.
